Not you. Not your partner. The pattern between you.
Most couples who come to therapy are not short on love. They are caught in a pattern: one partner's way of protecting themselves sets off the other's, and each reaction seems to confirm the other's fear. In Emotionally Focused Therapy (EFT), we call this the negative cycle.
Underneath it are attachment needs: to feel safe, to matter, to be able to count on each other. When those needs go unmet, we protect ourselves, and the protection, whether pressing, pushing, withdrawing or shutting down, can look like the opposite of what we want.
